To a/ZZ whom it may concern.-

Be it known that I, NORTH DOWLING, a citizen of the United States, residing at thecity of Philadelphia, in the county of PhiladelphiaJ and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Pulping and Compressing Garbage or Refuse Matter, of which the following is a specification. e

My invention relates to apparatus for treating garbage or Iefuse matter; and it relates more particularly to that type of such apparatus which is employed for compressing and pulping garbage preparatory to its incineration.

The principal objects of my invention are, first, to provide a simple, reliable, durable and comparatively inexpensive apparatus for compressing and pulping garbage; second, to provide the working parts of such an apparatus with adjustments, whereby the same may be adapted for the successful treatment of dilferent kinds ofv garbage or of garbage yin different states or conditions; and, third, toy

provide compact and reliable devices for transferring the partially treated garbage from one portion of the machine and for propyerly presenting'the same for treatment by' other portions thereof.

My invention consists of an apparatus for pulping and compressing garbage, comprising a hopper for receiving and feeding the garbage, a pair of positively driven spring controlled squeeze rolls having intermeshin'g fluted or corrugated surfaces, a pair of positively driven spring controlled calender rolls,

' claimed.

The nature, characteristic features and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming -part hereof; and in Whiching with thegear b', on the counter-shaft b.

Figure l, is a top or plan View of an apparatus for pulping and compressing garbage -embodyingfeatures of my invention; and Fig.

2 is a side elevational view partly in section 55 of the same. Y

' In the drawings, the base-pieces a, top pieces a', uprights o2, and tie-piece a, constitute the main frame of the machine.

' b, is a counter-shaft provided with a gear- 6o wheel o', and revolubly supported 'in bearings or boxes b2, formed integral with brackets c, bolted or otherwise secured to place upon the top-pieces a. 'I

c', are bridges bolted or otherwise secured 65 to place on top of the brackets c, and provided with cross-bars c2, that carry the feed hopper CZ. The brackets c, and bridges c', are provided respectively with webs or feathers c3, that constitute Ways or guides upon which 7o journal blocks d and d2, are affordedarange of movement. v

e and e', are squeeze rolls revolubly supported Yby the journal blocks d and d2, and provided with intermeshing iiuted or corrugated surfaces. These squeeze rolls are geared together by means of intermeshing spurwheels f and f', Fig. l, and the squeeze roll e', is also provided with a gear-wheel f2, mesh- 8o g, is a main driving-shaft revolubly supported in hangers g', bolted or otherwise secured to the under sides of the top-pieces a', and provided with tight and loose pulleys, not shown,and with a pinion g2, meshing with thegear-wheel b', so that the revolution of the main driving-shaft g, acting through the instrumentality of the pinion g2, and the gear- Wheels b and f2, causes the squeeze-roll e', to

be driven with a positive motion, and this 9o motion of the squeeze-roll e', is imparted to the squeeze-roll e2, by means of spur-wheels f and f. In use it is important that .the squeeze-rolls e and e', should be afforded a slight'range of motion in order to permit of 95 the passage of unusually large or hard objects between them. This result is accomplished by means of spiral-springs s, fitted at one of their respective extremities onto projections onthe boxes d', and at the other of their extremities into caps h, revolubly connected with one of the respective extremities roo of the setscrews h. These set-screws work in nuts formed integral with or secured to the brackets c, and are provided with han d-wheels h2, by means of which the force exerted by the springs s, upon the boxes CZ', may be increased or diminished. The material that passes between the squeeze-rolls `e and e', usually contains some solid matter and consequently it is necessary to provide means for maintaining a small space between the peripheriesof the same. This result is accomplished by means of set-screws fi, interposed between the boxes CZ and cZ2, and provided with jam-nuts fi', so that the space between the squeeze-rolls e and e', may be increased or diminished by means of the set-screws z', in order to accommodate the same for the successful treatment of garbage or other matter containing different quantities of solid matter; it being understood that the jam-nuts t", afford means for preventing the set-screws t'. from slipping after the squeeze-rolls have been adjusted.

j and 7" are Scrapers or doctor plates adapted to remove any material that may adhere to the squeeze rolls e and e', and connected with the top pieces a', by means of set-screws working in suitable slots in the end plates thereof, so that the doctor plates or Scrapers 3o j and j', may be readily adjusted in respect to the surfaces of the squeeze-rolls e and e.

k, are standards rigidly secured to the base j pieces a, and to the top-pieces a', and pro vided with ways Za', in which journal-.blocks k2 Aand 7c3, are aiorded a range of play.

blocks 7a2 and 7c3, and geared together by means of spur-wheels 7a4 and 765, Fig. l. One of these calender-rolls Z', is driven by a gear-wheel la, meshing with the pinion g2, ot' the drivingshaft g, so that the revolution of the drivingshaft g, acting through the instrumentality of the pinion g2, and gear-wheel 7c, imparts motion to the calender-roll Z', and the motion of the latter is imparted through the instrumentality of the gear-wheels 7c and 705, to the calender roll Z.

r:mare set-screws provided with hand-wheels m', and having their respective extremities resting upon the journal-blocks 7a2. These set-screws m, engage nuts n, provided with feathers n', working in suitable grooves cutor otherwise formed in the lower portions of yokes o, secured to the standards 7c.

s', are spiral-springs interposed between the nuts n, and the upper portions of the yokes o, and adapted to permit of the shifting of the bearing blocks 7a2, of the calender roll Z,in order to permit of the passage of the material between lthe calender rolls. The tension of the springs s', may be increased or diminished by turning the hand-wheels m', in one direction or the other, whereby the nuts fn, are shifted on the set-screws m; it being understood that feathers fn', prevent rotation of the nuts n.

1J, is an endless belt or conveyer traveling around the calender roll Z and around a series of pulleys p', mounted upona shaft p2, journaled in blocks 293, aorded a range of movement in guides p, secured to the basepieces a, and to one set of uprights a2.

q, are set-screws working in nuts in the guides p, and provided with hand-wheels q', and with collars q2, working in yokes secured to the blocks p3, so that the hand-Wheels q', aord means for tightening the endless belt or conveyer p. i

o" and r', are doctorplates or Scrapers adapted to remove any material that may adhere to the calender-roll Z, and endless-belt or conveyer p, and connected with brackets r2, by means of bolts working in slots r3, Fig. l, so that the doctor-plates or scrapers may be readily adjusted.

t, is a platform adapted to support the upper portion of the belt or con veyer 19, and provided with side-rails t', for preventing material deposited from the squeeze rolls e and e', from falling off at the sides or edges of the belt or conveyer p.

a, is a V-shaped evener adapted to distribute the material deposited upon the belt or con veyer p, toward the side rails t', and evenly over the sa1ne,so thatit may be properly presented between the calender rolls Z and Z. This evener a, is preferably connected to the main-frame of the machine by means of bolts working in slots a', in the hangers that carry the evener, so that the latter may be adjusted in respect to the belt or conveyer in order to insure a proper distribution of the material Z and Z', are calender-rolls journaled in the l being carried thereon.

The mode of operation of the hereinabove described apparatus, is as follows :-The garbage having been drained and disinfected or in its normal condition, is introduced into the hoppercZ, and passes between the iluted or corrugated surfaces of the squeeze rolls sand e. These rolls serve to pulp and squeeze the garbage and deliver it upon the endless belt or conveyer p. The latter carries the partially squeezed and pulped material toward the calender rolls Z and Z. However, before the material is delivered to the calender-rolls Z and Z, the evener u, spreads it uniformly over the belt or conveyer p. The even and uniform mass is then carried by the belt or conveyer 19, between the calender rolls Z and Z, and the latter serve to complete the pulping and squeezing operations, so that garbage is delivered from the calender rolls Z and Z', in a thoroughly pulped and squeezed condition and may be readily incinerated or otherwise disposed of. It may be remarked that any liquid that is squeezed out of the garbage during the above described treatment may be permitted to fall intoa suitable receptacle at the base of the main frameand from which it may be drained oit and disinfected.

Having thus described the nature and objects of my invention, what I claim'as new, and desire to secure by Letters Patent, is-
